Why Bomag BW 177 D-4 Construction Equipment engine does not start?
- S
  Sarah BushJul 31, 2025
  There are several reasons why your Bomag Construction Equipment engine might fail to start. It could be due to a defective starter, an empty fuel tank (in which case, fill and bleed the tank), temperatures below the starting limit (use winter fuel and engine oil appropriate for the ambient temperature), a clogged fuel filter (change the filter), leaking fuel lines (check and tighten connections), a discharged or disconnected battery (tighten pole clamps and check cable connections), or defective injection valves or pump. It is recommended to have a specialist examine the starter, or injection valves if those are the cause of the issue.

What to do if Bomag BW 177 D-4 engine overheats?

  Mary HallAug 4, 2025
  If your Bomag Construction Equipment engine overheats, shut it down immediately. The issue could be due to extremely soiled cooling fins on the radiator (clean them), a defective injection valve, a low engine oil level (top up to the upper dipstick mark), an incorrectly adjusted injection pump filling capacity, restricted cooling airflow (clean the cooling air duct), or a loose or broken V-belt (tension or replace it). It is recommended to have a specialist examine the injection valve or adjust the filling capacity of the injection pump.

  halldeborahAug 9, 2025
  Poor engine power in your Bomag Construction Equipment can stem from several causes: an engine oil level that's too high (drain to the upper dipstick mark), a dirty air filter (clean or change it), a defective exhaust gas turbo-charger, a leaking charge air hose (check the fastening and connections), incorrect valve clearance (adjust the valve clearance), or a defective injection valve. It is recommended to have a specialist examine the turbo-charger or the injection valve.

Why Bomag BW 177 D-4 Construction Equipment engine starts poorly and works irregularly?
- S
  Sarah JacksonAug 13, 2025
  If your Bomag Construction Equipment engine starts poorly and runs irregularly with poor power, possible causes include low battery power, loose or oxidized battery clamps (have the battery checked, clean and tighten the clamps, and apply acid-free grease), using engine oil that is too viscous (use oil suitable for the ambient temperature), a restricted fuel supply (change the fuel filter), incorrect valve clearance (adjust the valve clearance), a defective injection valve, leaking injection lines (check for leaks), a defective turbo charger, a dirty air filter (clean or replace), or excessive play in the throttle cable (adjust or replace the cable). It is recommended to have a specialist examine the injection valve or the turbo charger.

What causes excessive exhaust smoke in Bomag BW 177 D-4?
- T
  Timothy KingAug 18, 2025
  Excessive exhaust smoke from your Bomag Construction Equipment could be due to several factors: an engine oil level that is too high (drain the oil to the upper dipstick mark), a dirty air filter (clean or replace it), a defective exhaust gas turbo-charger, poor compression due to burned or broken compression rings or incorrect valve clearance (have compression rings and pistons examined, adjust the valve clearance), or simply incorrect valve clearance. It is recommended to have a specialist examine the turbo-charger.

What does it mean when charge control light lights during operation in Bomag BW 177 D-4?
- J
  Joshua JonesAug 21, 2025
  If the charge control light illuminates and the warning buzzer sounds during operation of your Bomag Construction Equipment, it could indicate that the generator speed is too low (check the V-belt tension and replace if necessary) or that the generator isn't charging the battery due to a defect in the generator or regulator. It is recommended to have a specialist examine the generator.

What to do if Bomag BW 177 D-4 Construction Equipment engine oil pressure is too low?
- J
  jasonjohnsonAug 26, 2025
  If the engine oil pressure is too low in your Bomag Construction Equipment (indicated by the control light and warning buzzer), it could be due to a low engine oil level (top up the oil) or leakages in the lubrication system. If there are leakages, immediately shut down the engine and check the fittings on oil lines, the lubrication oil filter, and the oil cooler for leaks, tightening the fittings if necessary.
